Has anyone got the solutions for the paper
I agree with thisimo i disagree
q14 this year felt much more inaccessible than last year
might be due to exam stress but i did much worse in this exam than last years q14 where i got 9-10/15. the vector q much easier, projectile much easier to gain marks, the 4 marker differential equation was literally just free marks. so yeah. (binomial was hard tho i got 0/4 lol)
he's righttf are you smoking little boy if you did 2022 you would have pissed your pants stop coping
what are you on aboutQ14 seems time consuming but 14abc i. all seem doable 14cii seems hard to get full marks but definitely easier than the stats question from 2022
just tryna be nice browhat are you on about
Sounds right to meHey wondering for question 12e - the volume one, is it an appropriate method to find integral from 4 to 12 of f(y)^2 (Normal volume of revolution), then add the volume of a cylinder with height 10 and radius 4? Surely. ik im just overthinking but i bombed that exam
Yes, and it should give you the answer cubic units.Hey wondering for question 12e - the volume one, is it an appropriate method to find integral from 4 to 12 of f(y)^2 (Normal volume of revolution), then add the volume of a cylinder with height 10 and radius 4?

Istg the people on this website are some of the most insufferable shitheads I've come across. "I'm gonna cry bc i might get 92 in a course I've finished".3u maths is not real
my past papers did not prepare me for that wtf... i was consistently 60+ for all past hsc papers and for this years test I feel like I absolutely bombed it. Usually q11,12,13 are a breeze, and I can get at least half of q14. This years i lost marks in question 12,13, and didn't get the majority of q14.
Was hoping for a 96/97, now its looking more like a 92
pls tell me im not the only one...otherwise im crying
Radius -10 and height 4… about the y axis. Made this mistake in the exam ripHey wondering for question 12e - the volume one, is it an appropriate method to find integral from 4 to 12 of f(y)^2 (Normal volume of revolution), then add the volume of a cylinder with height 10 and radius 4?

^^^^for 16 c i), the non-otherwise approach is to create a vector perpendicular to B called C = (b2, -b1).
area OAB = 1/2 * |OA||OB|sin(<AOB) = 1/2 * |OA||OB|cos(90 - <AOB) = 1/2 * |OA||OC|cos(<COA) = 1/2(OA . OC) = 1/2(a1b2 - a2b1)
since |OB| = |OC|
pretty sure this is the simplest you can get.
depends.Istg the people on this website are some of the most insufferable shitheads I've come across. "I'm gonna cry bc i might get 92 in a course I've finished".
youre quite the wordsmith. nicely put@notme123
I feel the exam had a reasonable gradient of difficulty - a non-ext2 student should be satisfied with comfortably getting through Q11-12, then wading through the wordy and pronumeral bloated Q13 and playing substitution games. Marks in Q14 will be sparse because each question really targets a sophisticated understanding of something niche in the syllabus, still well within the syllabus though!
